       6. The floor or wall covering as in  claim 1 ,
 wherein the top layers of the panels comprise on their upper surfaces another groove; 
 wherein the another groove of the top layers of the panels also comprises the grouting material. 
 
     
     
       7. A method for installing the floor or wall covering as in  claim 1 , the method comprising the steps of:
 providing floor or wall panels, for use in a floor or wall covering; 
 installing the floor or wall panels by mechanically coupling the floor or wall panels by coupling the male coupling parts with the female coupling parts; 
 applying grout into the recesses provided at the surface of the floor or wall covering between the floor or wall panels mechanically coupled to each other by the male coupling part and the female coupling part. 
 
     
     
       8. The floor covering, as in  claim 1 ,
 wherein the floor covering comprises floor panels, an elastic strip and a flexible sealing agent, 
 wherein the elastic strip is provided adjacent to an edge of the floor covering, 
 wherein the flexible sealing agent is provided above the elastic strip, 
 wherein the flexible sealing agent is provided adjacent to and in contact with the edge of the floor covering. 
 
     
     
       9. The floor covering as in  claim 8  wherein a skirting board is positioned onto the floor panels providing the edge of the floor covering,
 wherein the skirting board covers the elastic strip and the flexible sealing agent. 
 
     
     
       10. The floor or wall covering as in  claim 1 , wherein the recess comprises a first recess cut out or provided at the female edge; and a second recess cut out or provided at the male edge. 
     
     
       11. The floor or wall covering as in  claim 1 , wherein the grouting material is provided on a surface of the male edge substantially parallel with the panel surface and on a surface of the female edge substantially parallel with the panel surface. 
     
     
       12. The floor or wall covering as in  claim 1 , wherein the coupling parts are configured such that when installing the covering, a panel is arranged to be coupled via a substantially horizontal sliding movement with a snap effect of the panel relative to an already installed panel, wherein the tongue of the panel is arranged to be inserted into the groove of the female edge of the already installed panel with the snap effect. 
     
     
       13. The floor or wall covering of  claim 12 , wherein a rounding at the bottom of the nose is arranged for the installation and coupling of the panels via the substantially horizontal sliding movement with the snap effect.
